dave c closed FELIX-3378.
-------------------------
Resolution: Not A Problem
It was not a problem in how we profiled the OSGi environment. It was a problem
with the application that we did not handle correctly.
> class in bootclasspath cannot load osgi framework class

> Key: FELIX-3378
> URL: https://issues.apache.org/jira/browse/FELIX-3378
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Environment: Windows7,64bit. Java 1.6 jdk, Protege 4.1, Felix 2.0.4,
> OSGi R4
> Reporter: dave c
> Labels: newbie

> I work on a java profiler project. We have added our package to the
> bootdelegation path, so our code is found even though no explicit reference
> exists to our package. The problem seems to come when our code tries to load
> a class that is not our own.
> I am profiling Protege 4.1. We have some code running in a background thread
> which gets this error. I looked at the felix code for ModuleImpl, and find
> nothing obvious. Is there something I'm doing wrong that prevents our thread
> from finding this class? Or is this a limitation of the OSGi framework?
